There isn't really a cost estimate. It just says that it's not a $100 mod.
The derailleur is kind of out of my price range.
For brifters, how do I know if it'll be compatible with a certain derailleur _____? (If this is an issue)
My Mu P8 is an 8 speed. I read that there are a few (minor) problems using a 9-speed brifter with an 8 speed cassette?
@Lock: Thanks, that look like a good idea since my LBS' cheapest brifter pair starts out at $400. What would I do about the shifter? Bar end shifters? I saw one setup with their twist grip on an "accessory mount", I could try that and then move up to full brifters later.
Edit: Found a local ad, if I can get (2008 Ultegra) "Shifters and front and rear derailleurs, chain, b.bracket, Gossamer 172.5 double crankset 48/38" for $400, should I go for that?
